ELECTRIC INSTRUMENT FOR CAUTERY.

SPECIFICATION forming part of Leners Patent No. 703,369, dated July 1, 1902.

Applicationled March 8, 1902. Serial No. 97,326. (No model.) i

. T all whom t may concern:

Be it known that I, WALTER B. BATCHEL- LER, a citizen of the United States, residing at Chicago, in the county of Cook and State 5 of Illinois, have invented a new and useful Electric Instrument for Cauterizin g, of which the following is a specification.

My object is to facilitate the use of an eleetric current for cauterizing membrane in the Io nostrils, the mouth, and throat, arteries in a wound, or in any cavity in a person by providing an instrument that can be held in a persons hand and the current opened and closed at pleasure by the foretinger of the I5 same hand, while at the same timethe instrument and hand will not prevent the operator from seeing and examining the part to be cauterized and the application and effect of the cauterizing-current applied to the pa- 2o tient.

My invention consists in the construction, arrangement, and combination of parts, as hereinafter set forth,pointed out in my claims, and illustrated in the accompanying' drawings, in which- Figure lis a perspective view ofthe instrument adapted to be connected with a battery and also adapted for holding and manipulating advantageously a searing-Wire and opening and closing and controlling` the electric current. Eig. 2 is a longitudinal sectional View showing conductors embedded in one of the separable parts of the handle and the form of the circuit-closer. Fig. 3 is a view of the other portion of the handle, showing one of the conductor-wires in position for prod ueing a circuit.v

The letter A designates an elbow-shaped handle composed of two mating parts detach- One end portion of the handle is straight on its top surface, so a person can hold it in the line ot' vision and sight over it, as required, to look into a persons mouth or other cavity when using the instrument.

They are preferably made of hard rubber and securely cover and insulate the electric conductor embedded therein and fastened together by screws. The lower portion of the handle is adapted in shape and size to be con- 5o veniently grasped in a persons hand, and the upper portion has a straight top surface over per end of the handle.

which a person can sight when operating the instrument. A cavityB in the underside ol the upper portion is adapted to serve asa chamber in which ends of two pieces of the conductor will normally rem ain separated. A trigger C is pivoted in the cavity and adapted in form for closing the circuit. One of the conductor-wires CZ, laid in a groove in the handle, extends into the top portion of the cavity 6o and the other separate piece d into the lower portion, as shown in Eig. 2, in such a manner that their ends will be in parallel position and will not contact with each other. A conductor thus made of two pieces of wire is adapted to be detachably connected with a wiref, extended through a metal tube iixed to the part A and to a battery from the lower end of the handle and also adapted to be detachablyconnected with one end of a cauteriZing-wire 'vo that extends through la metal tube at the up- A second wire conductor 7L extends from one end of the handle to the other andis adapted to be connected with a wirej", extended through a metal tube and to a battery and the other end of the cauteriZing-wire g, that extendsinto a tube, as required, to establish a circuit. The conductors are thus embedded, concealed, and protected in the handle,` which serves as an 8o armature for the conductors as well as a means for manil'rulating the cauteriZing-Wire.

Binding-screws 71, for connecting and fastening the conductor-wires embedded in the handle with the cauterizingavire g are seated in the metal tube at the upper end of the handle, and corresponding screws are seated in the metal tubes at the lower end of the handle, as required, for detachably connecting a cauterining-wire with the instrument and the 9o instrument with a battery.

It is obvious that when a person has hold of the lower portion of the handle he can readily close the circuit instantly by lingerpressure upon the trigger and open the circuit instantly by relaxing such pressure.

IIaving thus described the purpose of my invention andthe construction, arrangement, and combination of the diftei'ent parts, its practical operation and utility will be readily understood by persons familiar with the art to which it appertains.

`What I claim as new, and desire to secure by Letters Patent, is

l. In an instrument for eauterizing, an elbow-shaped handle straight on the top of one end portion and the inner end and under side of the straight portion having;` a Chamber Iand vthe ends of two pieces of a wire Conductor exner end of the straight portion, a trigger pivoted in the cavity, two pieces of a Wire conductor embedded in the handle and extended into the Cavity, a third piece of Wire conductor embedded in the handle to extend from one end to the other and binding-screws seated at the upper end of the handle for conneeting the ends ol a oauterizinfg-wire with the Wires embedded in the handle and binding-screws at the lower end of the handle for connecting,` Wires extending from a battery, arranged and combined to operate in the man ner set forth, for the purposes stated.
